To all 'whom it may concer/n.:

Be it known that I, CHARLES BALOUGH, a subject of the Emperor of Austria-Hungary, residin at Springfield, in the county of Clark an State of Ohio, have invented certain new and useful Improvements in Pressure-Governors, of which the following is a specification.

This invention relates to improvements in governors, the governor shown being one particularly designed for regulating the speed of internal combustion engines an being arranged to be operated by uid put under pressure by the engine.

The object of the invention is to provide a governor which will be simple in construction and effective in operation and also one in which friction of the moving parts will be reduced to the minimum.

In the accompanying drawings Figure 1 isl a side elevation of a portion of an internal combustion engine, showing my improved governor applied thereto, the governor and some of the parts of the engine being shown in section.

Fig. 2 is a section on the line 2-2 of ig. 3 is an enlarged view of a portion of the devices shown in Fig. 1. In the present instance, I have illustrated the governing mechanism connected with the oiling system of the engine, this system being such as is now commonly in use in connection with automobiles. ln carrying out the invention, I employ a piston or plunger, 1, located in a suitable chamber or cylinder which is in direct communication with the oil. It is immaterial` at what particular point this plunger is applied, but in the present case I have shown the plunger located in the hollow hub 2 of a gear 3 which forms a part of the operating mechanism connected with the engine. The bearing 4; for the gear hub is in communication with an oil pump 5 through the passageway 6 and oil under pressure will find its way to the interior of the hub 2 through the groove 7 and opening 8 leading from the groove to the interior of the hub. rlhe piston 1 has connected therewith a rod 9 which is slidmounted in guides 10, the rod being provided with a {iattened portion 11 and one of the guides provided with a correspondingly shaped orifice to prevent the rod from turning. Connected to the end of the rod is a head 12 provided with an inclined surface 12a. In the present case I have shown the valve mechanism as being located in the intake manifold 13. 14 is a stationary sleeve located in the chambered portion of the support 15 for the manifold and extending through the manifold into a chambered portion 16. Slidably arranged. in the stationary sleeve 14, is a movable sleeve 17 closed vat the top and bottom but provided with ports 18 arranged to coperate with ports 19 in the stationary sleeve 14; these ports being arranged in the manifold 13. The lower end of the closed sleeve 17 has a stem 20 which extends down through the support 15 and has its lower end provided with an antifriction roller 21 which is maintained in contact with the inclined surface 12 of the piston rod by a spring 22 interposed between the upper end of the sleeve 17 and the closure 23 for the chamber 16. The cap 21 which closes the upper end of the movable sleeve 17 projects laterally beyond the same so as to coperate with the stationary sleeve 14 to provide a stop.

When the piston 1 is at its extreme inner position in the hollow hub, the ports 18 and 19 will be in complete registry with each other so as to` allow the maximum amount of fuel to pass through the intake manifold. As the speed of the engine and consequently the pressure of the oil, increases the piston will be forced outwardly causing the inclined surface of the piston rod to force the stem 20 and sleeve 17 upwardly against the tension of the spring so as to partly or completely close the ports. As the speed of the engine, and consequently the iow of the oil, decreases the spring 22 will force the parts in the opposite direction to increase the supply of fuel. The closure 23 is in the nature of a screw-threaded plug which provides means for adjusting the tension of the spring.

Having thus described my invention, I claim p 1. In a governing mechanism for a motor, a source of motive energy for said motor together with driven devices, a source of lubricating liuid pressure controlled by the motor, a piston located near the center of one of the driven devices arranged to be acted upon by said uid, a valve for the motive nosa energy comprising a slidable ported sleeve, and a connection between said piston and said sleeve.

2. ln a governing mechanism for a motor, a source of motive energy for said motor, a source of uid under pressure controlled by said motor, a ypiston in communication with said fluid, a spring pressed ported sleeve 'for controlling said motive energy, an inclined block connected with said piston, and a'valve stem connected with said sleeve coperating with said block;

3. In a overning mechanism for a motor, a source or motive energy for said motor, a source of fiuid under pressure controlled by said motor, a piston in communication with said fluid, an inclined block connected with said piston, a spring pressed valve comprisin two ported sleeves one of which is movable with respect to the other, and a stem connected with said movable sleeve and cooperating with said inclined block.

4. In a governor for internal combustion engines, a source of fuel together with an intake manifold for the same, a source of fluid under'pressure controlled by said motor, a piston in communication with said fluid, a piston rod connected with said piston having an inclined surface, a fuel valve arranged 1n said manifold consisting of two ported ',sleeves, one 'of which is movable with respect to the other, a valve stem connected to one of said sleeves coperatin with said inclined surface to move sai sleeve in. one direction, and a spring for moving said sleeve inthe opposite direction. 5. In a governing mechanism for a motor, a source of motive iuid for said motor tokgether with gear mechanism driven by said motor, a source of lubricating vifuid under pressure controlled by said motor, a cylinder and piston arranged near one of said driven devices whereby the piston cylinder ,willi be in line with the bearing for the driven device, said piston being arranged to be acted upon by said lubricatlng Huid, and devices for controlling said motive` fluid, substantially as specified.

in testimony whereof, I have hereunto set my hand this 13th day of April, 1916.

CHARLES BALOUGH.
